Answer:
Dave had most fun for 1.5 minutes.
explanation:
Let the "fun time" be f
total time * portion of time fun = fun time
[tex]\sf t * p = f[/tex]
[tex]\sf 6 \ * \frac{1}{4} = f[/tex]
[tex]\sf \frac{6}{4} = f[/tex]
[tex]\sf f = 1.5 \ minutes[/tex]
Question was for how many minutes, Dave had fun, so he had fun for 1.5 minutes
Let that half be x
So
[tex]\\ \rm\Rrightarrow x(4)=6min[/tex]
[tex]\\ \rm\Rrightarrow x=6/4[/tex]

A surface area of a cube is related to its volume V by A = 6. V(2/3). If the volume of a
cube is 35 cubic centimeters, what is its surface area to the nearest square centimeter?
The surface area of the cube is 64 cm².
What is volume?Volume is the amount of space that is enclosed within a container.
To calculate the surface area of the cube, we use the relation below.
Formula:
A = 6V[tex]{2/3}[/tex]............ Equation 1Where:
A = Surface area of the cubeV = Volume of the cube.From the question,
Given:
V = 35 cm³Substitute this value into equation 1
A = 6(35)[tex]{2/3}[/tex]A = 6(10.6999)A = 64.2 A = 64 cm²Hence, The surface area of the cube is 64 cm².

A.
Step-by-step explanation:
I know I am late. Hope this helps you understand at least.
For a 30 60 90 triangle the side opposite to the 60 is always x√3.
The hypotenuse is always 2x
And the site opposite to the 30 is always x.
Since x is 3 you would replace the x in x√3, with 3.

A rose garden in the city park is rectangular and is 9 m wide. If the area of the rectangle is 144 m², what is the length of the garden?
Answer:
Length = 16m

Area of a rectangle = Length * Width
144m^2 = Length * 9m
Divide both sides by 9m
Length = 16m
A small boat leaves the dock at Camp DuNuthin and heads across the Nessie River at 17 miles per hour, relative to the water, at a bearing of S60° W. The river is flowing due east at 6 miles per hour. What is the boat's true speed and heading? Round the speed to the nearest mile per hour and express the heading as as a bearing with the angle rounded to the nearest tenth of a degree
The speed of the boat will be 12.18 mph, and the angle of its direction measured from the positive x-axis will be 224.3°
What we can say about the boat speed?
First, let's define North as the positive y-axis and east as the positive x-axis.
In this coordinate axis, the angle S 60° W is equal to 210°.
Then the velocity of the boat will be:
v = (17mph*cos(210°), 17mph*sin(210°))
Now we also need to add the speed of the river, which is 6mph to the east, then the final velocity of the boat will be:
v = (17mph*cos(210°) + 6mph, 17mph*sin(210°))
v = (-8.72mph, -8.5 mph)
Then the speed of the boat will be:
|v| = √( (-8.72mph)^2 + (-8.5 mph)^2) =12.18 mph
And the angle, measured from the positive x-axis, will be given by the arctangent of the quotient between the y-component and the x-component:
Atan(-8.5 mph/-8.72mph) = 224.3°

How much of the pizza has he eaten in all?
Give your answer as a fraction, reduced to lowest terms.
Answer:
I think 4/10 pizza he had ate .
The amount of the pizza he ate will be 9 / 40.
What is Algebra?Algebra is the study of graphic formulas, while logic is the interpretation among those signs.
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.
There are ten pieces of pizza.
Anthony ate 1/8 of the pizza for dinner.
Then the amount of pizza left will be
⇒ 1 – 1/8
⇒ (8 – 1) / 8
⇒ 7/8
He ate 3/10 for a bedtime snack.
Then the amount of the pizza will be
⇒ 7/8 – 1/10
⇒ 31/40
The pizza has he eaten in all.
Then the amount of the pizza he ate will be
⇒ 1 – 31/40
⇒ 9 / 40
Then the amount of the pizza he ate will be 9 / 40.
